Certification

So OCZ introduced the new 750W MK II series with an 80+ Silver certification, tested by the 80PLUS organization (the people that certify and test efficiency). But what does such a certification entail?

Well, we have bronze, silver, gold, and platinum certifications. A PSU that is certified 80 PLUS Gold or 80 PLUS Platinum is more efficient than a normal unit. Below youll find a table that shows what efficiency levels a PSU has to achieve at a given load to make the grade for a specific certification level.

Efficiency at 20% Load

The power supply is certified by the 80PLUS organization to deliver an 88% energy efficiency at 50% load (which equals with a Silver label) and also comply with the ErP (Energy Related product) directive to ensure less than 1W of power is used in passive standby and off modes.

So then, things have been quiet surrounding PC Power and Cooling but they are back with new series of power supplies that were developed to offer high efficiency and quiet operation while also using a modular design.

The Silencer Mk II Series comes backed with a very nice 7-year Warranty for your peace of mind.

The PSU specifications list a 135mm double ball-bearing fan for quiet operation, 80PLUS Silver certification, as well as a low noise and ripple design. But let's move onwards to the photo shoot.

The new PSU also improved on the audibility front as it comes with a switch, enabled it and up-to 600 Watt (!) the fan will remain disabled and at that load your PSU merely lukewarm. The 1200W PSU is massive in performance, the one massive 99.5A 12-volts says it all really. Excellent for multi-GPU solutions and hardcore overclockers.

PC Power and Cooling Silencer MkII 750W PSU reviewThe new model PC Power & Cooling power supply is their Silencer Mk II series of PSU's. It's the 'bloke' PSU series again with a simple design, and hey -- nothing is modular so the PSU certainly is a squid inside your system with all the tentacles (wires), but yeah .. lots of you don't really care about cable management, they just want the best of the best and sure ...as you'll learn you can't really complain about the essence that is the Mk II Silence 750W power supply.
